After printing the eyesonff walkthrough for FFX-2, it has been a small project of mine to get 100% completion; I NEED the ending with Tidus (Despite what my bastard therapist says)

Anyways, I had completed about 37% of the game when I get to the part where you comandeer clothes at Gagazet (I'll keep this spoiler free). But later, when I finally pay all the 100,000 to you-know-who, the completion percentage won't go to 38. I immediately looked at the printed guide to find out what I did wrong, and pinpointed it: I approached the clothes part wrong and therefore did not get the "complete" cutscene.

What I need to know is if the game will give you the perfect ending with a small margin for error. Or do I have to go Kill Bill on Squaresoft's heiny? *sharpens katana*
